Why must you use the rectangular
tubing?
The first shape that comes to our
mind once we hear about the tube hangrail is that it is round, because the
dictionary describes a tube as something which is a hollow elongated pole and
round in shape. But a Rectangular Hangrail Tube although
somewhat similar in meaning, differs a bit in terms of its shape. It is also a
hollow elongated pole, but instead of round, the sides are flat in shape. This
shape has many different applications. It can especially be used in situations
where the round shaped tube fails to deliver the requirement fulfilled by a
flat shaped tube. It’s particular rectangular shape allows it to be used for
some particular applications. Since the surface is flat, it makes joining one
hangrail with the other simpler and easier. It is also much stronger when
compared with the circular profile.
Material of the tube
Most of the rectangular tubes
available in the market are made up of the following materials: steel,
aluminium, PVC, fiberglass, and carbon fibre. Below is a brief description of both
the advantages and disadvantages of each of these materials:
Steel: Steel is a very common material for
making these hangrails, the first reason being, it is very strong, which is
obviously the important aspect. The second reason is that it is relatively less
expensive when compared to other materials. It again has drawbacks, which is-
they are very heavy and also corrode very easily.
Aluminium: Aluminium is used because of its
lightweight features when compared to the weight of steel. It is also corrosion
resistant. Another advantage of using this material is that it is a good
conductor of heat and electricity, which are desirable properties in certain
situations. But they can be expensive when compared to steel.
PVC: PVC, which stands for Polyvinyl Chloride, is a
widely-used plastic which is resistant to corrosion as well as lightweight.
When compared to the price of aluminium and steel, it is way cheaper to use PVC
to make the Rectangular Hangrail Tubing. But its disadvantage when
compared to the other two materials is its strength. It cannot be used for
structural purposes.
Fiberglass: Fiberglass is available in many
varieties and it depends upon the glass fibre used and also the resin
reinforced in it. Fiberglass is very lightweight but it is also very strong,
which is much stronger than steel or aluminium. It is also highly resistant to
corrosion. On the other hand, they are more expensive than steel or aluminium.
Carbon Fibre: it is made with carbon
fibre in place of glass fibre. Thus, it has properties almost similar to glass
fibre, but even stronger than glass fibre. The biggest disadvantage for which
it is preferred less is its cost.
Which of these materials will be
appropriate for you, depends on the application of the Rectangular Hangrail
Tubing.
